Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Help please. I'm a veteran Windows user who has become disgusted with MS and wants to learn Linux. However, I'm having trouble with what I would consider are elementary tasks. It took me forever to update my nvidia driver and now I'm trying to get my sound to work. I'm soooo frustrated I could throw the whole thing out the window.
I'm using Mandrake 9.1 and KDE. I have Creative Labs Inspire 5.1 5200 speakers and a on-board C Media CM8738 chip. After installation the sound worked however nothing was coming out of the center channel. I poked around on the net and saw that some people fixed the problem by install Open Source Sound. I downloaded it and installed it and ran the audio test. It worked.
However, I read that OSS and KDE conflict unless you load KDE second. Well, I didn't know how to 'undo' the installation and now, sure to its word, when I boot up i get a message saying something couldn't be found and the sound doesn't work. How do I get OSS to work with KDE, change the configuration back to default, or whatever.
Someone help me please. I'm not only a newbie, but I feel like a complete fool because I can't even install drivers and troubleshoot them. I want to use Linux over Windows, I hear so many good things but it's driving me mad trying to use, work and understand it.
I was under the impression that OSS support is compiled into the kernel and not so much a factor of KDE support. I could be wrong but the last kernel rebuild I did the other day (2.4.21) had a section under sound for OSS support. You may need to recompile the support and not mess with KDE until the kernel supports the sound system, then tweak KDE's settings to match it. Just a thought...
Does it give you the path to where it is looking?
If it does go there and see if it exists.
run locate <what it is looking for>
Does it exsist
Yes - is it in your root path? echo $PATH$ from root
No - Go find it
just a start
Perhaps I didn't illustrate my point clearly Corin.
1. I have no idea what I am doing (concerning linux).
2. I wouldn't know what's better, I have no opinion on any of it (yet).
I'd love to stick with ALSA, if that's the default or whatever. I don't know that OSS is stone age compare to ALSA (but I do now). I don't know the terminology. I don't know what anything is, let alone what it does. I don't know where anything is. Essentially I don't know squat. I've used MS products for 20 nearly twenty years and I want to be rid of Microsoft forever (except for playing games )
I'm so new to Linux I feel like a complete moron. I've started reading to learn everything i can but I haven't even reached a basic understanding of Linux yet. I'm still in the ignorant stage.
I'm going to try what Cooner suggested and go from there. I just want to get back to what the default sound set up was and go from there. But I don't know what files were modified, where they are, or how to get them back to the way they were. After that, then i'll do what corin suggested.
Hey, when I started using Unix, I was a complete and ignorant know nothing too. We all have to start from the sample place so there is no shame in not knowing anything, provided you are prepared to learn (which you ovbviously are prepared to do).
But I ask that you would at least try issuing the command in your X terminal emulator (konsole or whatever in your X session using KDE)
and see if the program runs in your terminal emulator window.
The look for a bar for the CENTER channel and see if that is muted (M) and what the volume level is set to.
To move around you just use the arrow keys <- and -> M to mute or unmute, and the arrow keys UP and DOWN to change the volume level.
Give this a try and we will at least know if you have ALSA sound support, and if so, if it is just a very simple fix to your problem.
And no you do not have to be in a specific directory to run alsamixer.
What I am pretty sure it is saying is, you do not have the ALSA modules loaded, because it cannot open the default [sound] device.
So maybe for your system, the default sound drivers are the OSS modules, which would surprise me greatly since I would have expected Mandrake 9.1 (you are doing this on a Mandrake 9.1 system?) would be using ALSA by default.
Did you get any hard print documentation with Mandrake 9.1? I'm just wondering if you could do a quick check in the installation/user manual to see if it makes any mention of sound drivers?
I'm nearly certain that my default drivers were ALSA. I remember seeing it there somewhere.
THe only reason I tried the OSS driver was because I read somewhere that the C media CM8738 chip had trouble working properly but was remedied by OSS . Looks like that was possibly incorrect. However, this is what happens when a novice goes messing around with things he shouldn't have. I should have looked here first but being new I didn't know this place existed.
I downloaded Mandrake from their website, so the only docs I have are whatever I can find on their site or in a readme somewhere....
Hey, again I have to say, if you don't go around messing with things and breaking them, then you never learn how things work or how to fix them. I'm not a Mandrake expert by any means, since I do not have a Mandrake system. However there is a system configuration tool something like drakeconfig or drax is there not, which you should learn to use, until you become more of an expert of getting your hands dirty with the files underneath.
Now using this configuration program it should be possible to delete your current sound scheme and re-install it. I'm not talking about re-installing the system, or even the sound module files themselves, just the sound configuration files.
So can you fire up "drax" (?) and go to a section marked sound?
My apologizes if this sounds like the blind leading the blind, but as I say, I am not familiar with Mandrake.
I should point however that despite different distributions having different configuration interfaces (Mandrake - drax, Suse -Yast) what they are actually changing under the hood, is all pretty much the same thing. Apart from possible differences in version revisions, ALSA on SuSE is the same as ALSA on Mandrake is the same as ALSA on RedHat etc.
Originally posted by DeadDireWolf device /dev/dsp can't be opened (no such device)
This means that no driver module has been loaded to enable the device.
This is not good news.
The sound server will conitnue using the null output device.
This means that to prevent programs which emit sounds from getting stuck because they are always waiting for the buffer of the sound to get played out by the sound device to be emptied, the sounds are going to be sent to a bitbucket.
I looked in the /dev/dsp and it looks like it exists.
Yes the device file will exist, but there is nothing connected to it. If you also look in /dev you will see /dev/hda /dev/hdb /dev/hdc etc
Now if you are using an IDE disk, then it will be referenced by /dev/hda, but the /dev/hda is just a pointer to the disk driver in the kernel.
Unknown Driver - Error: The "" driver for your sound card is unlisted.
This is the worst news possible. It means that the version of ALSA which comes with Mandrake 9.1 has not been configured for your sound card because, presumably, it is not supported, or because it has failed to detect your soundcard (which is quite possible).
Can you do an
rpm -qa | egrep -i alsa
to see which version of the ALSA packages you have installed?
obviously substituting your actual Kernel version number for Your_Kernel_Version.
If this file is present on your system, then you have an adequate ALSA installation and you can just follow the instrusctions at the URL above starting in the section
Setting up modprobe and kmod support
about half way down the page.
If you do not have ALSA installed on your system, then you are either going to have to install the rpms from your Mandrake ISOs or get even better since ALSA 9.6 is now out (very hot and fresh 2003-07-28), get the rpms from
